Analysis,evaluation and interpretation of measured signals become important components in engineering research and practice,especially for material characteristic parameters which can not be obtained directly by experimental measurements.The present paper proposes a hybrid-inverse analysis method for the identification of the nonlinear material parameters of any individual component from the mechanical responses of a global composite.The method couples experimental approach,numerical simulation with inverse search method.The experimental approach is used to provide basic data.Then parameter identification and numerical simulation are utilized to identify elasto-plastic material properties by the experimental data obtained and inverse searching algorithm.A numerical example of a stainless steel clad copper sheet is considered to verify and show the applicability of the proposed hybrid-inverse method.In this example,a set of material parameters in an elasto-plastic constitutive model have been identified by using the obtained experimental data.
